Lastly, I always leave the compressor attached - never longer than maybe 30-40 minutes. I've been doing this for a considerable time now and hundreds of castings, from snakeskins to wood. The resin seems to always go to a gel state in from 10-20 minutes - and when removed from the pot after 30-40 minutes, it is totally set - not hard as a rock, but set. I then remove it and take it inside to finish the curing state. I normally remove the castings from the molds in 2 or three hours. They still feel a bit "sticky", but I let them set overnight. Then I saw them, drill and get down th road.
Does it matter if the pressure pot is located outside [fresh air - as in a garage] or inside [as in a basement workshop - like mine]?
